Hello,

A new link is provided to draft. Note that the submission date of the draft has changed since the previously uploaded draft. 

http://www.ietf.org/internet-drafts/draft-lindquist-mmusic-sip-rtsp-00.txt

Best Regards,

PS- The reason for change in submission date was due to the portal for uploading drafts silently rejected the upload. The rejection was due to date uploaded was off by more than 3 days from the date in the draft.

>    The Session Initiation Protocol (SIP) is widely used for establishing
>    multimedia sessions, whereas the Real Time Streaming Protocol (RTSP)
>    is a protocol for use in streaming media systems.  RTSP has a dual
>    role: it establishes a media session for the delivery of streaming
>    media as well as controls the streaming session once it has been set
>    up.  Since RTSP is also used for session establishment, there exists
>    an overlap between the functionality provided by SIP and RTSP.  In
>    this document, we analyze a model in which SIP and the SDP offer/
>    answer model are used to set up a streaming session with an RTSP
>    control channel and one or more media delivery streams.  Such a model
>    is beneficial since it allows the reuse of current architecture and
>    functionality (e.g., authentication, charging, and QoS) established
>    around SIP also for RTSP-based streaming.

> If there are any questions or comments on the new draft we will be glad to answer them.
